I needed to upgrade my sounder last year and went with one of the 5" units they had at that time. It's a good enough for most people but its kind of a dumbed down, easy to use means that there are very few settings you are able to change at all, so easy to use. You can change the colour of the display though. For people who like to dial it in you just can't cause there's no settings. The nicest thing is the display is real easy to see in any weather I've been in and that's important for sure. My other plotter can be dialed in up the ying yang but only the driver can see the screen cause of glare or other issues. It's my stand by unit that can be seen from a distance, I'd probably replace it if it died just for that. Charts and depth sounder are easy to use and see, just not pro quality features.
